Examples of voldemort.utils.HostNamePair

voldemort.utils.HostNamePair
HostNamePair represents a pairing of a host's external and internal names. Depending on the network topology, a given server may be referenced by a different name to systems outside its local network than the name used internal to the local network.
An EC2 instance, as an example, has two different host names. The external name (e.g. ec2-72-44-40-78.compute-1.amazonaws.com) and an internal one (domU-12-31-39-06-BE-25.compute-1.internal).
For systems which have only one name, both the external and internal host names should be the same. That is, they should be identical and neither should be set to null.

                String externalHostName = line[0];
                String internalHostName = line.length > 1 ? line[1] : externalHostName;
                hostNamePairs.add(new HostNamePair(externalHostName, internalHostName));
            }
        } catch(IOException e) {
            throw new RuntimeException(e);
        } finally {
            if(li != null)
